Using source code

You can download the source code from the GitHub repository and compile the software from the source, as follows:

1. Before you begin, let's first install the dependencies of Git; execute the following commands as the root user to do so:

      $ apt-get update -y 
      $ apt-get install build-essential checkinstall libreadline-gplv2-
         dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-
         dev libc6-dev libbz2-dev -y   

1. Now, let's download Python (https://www.python.org) using the following command from Python's official website. You can also download the latest version in place, as specified:

      $ cd /usr/local
      $ wget https://www.python.org/ftp/python/3.4.6/Python-3.4.6.tgz  

1. Now, let's extract the downloaded package with this command:

      $ tar xzf Python-3.4.6.tgz  

1. Now we have to compile the source code. Use the following set of commands to do so:

      $ cd python-3.4.6
      $ sudo ./configure
      $ sudo make altinstall  

1. The preceding commands will install Python on your system at /usr/local. Use the following command to check the Python version:

      $ python3 -V
